IMPROVED APPARATUS FOR `IEIVIP'IYIII'G- THE COOLING-TUBES OF BONE-BLACK FUR- NACES.

The Schedule referred to in these Letters Patent and making part of the same.

T o all whom, tt may concern:

Be it known that I, EUGnN Limena, of Cologne, in the Kingdom of Prussia, have invented a new and improved Apparatus for Emptying theOooling-Tubes in theaccompanying sheets-of drawings, in which- Figurel represents a vertical longitudinal section of a set of furnaces, witltmyimproved apparatus applied thereto.

Figure 2 is a detail vertical longitudinal section, on an enlarged scale, of theimprovcd apparatus, showing part of the cooling-tubes.

Figure 3 is a vertical transverse section of the same.

Figures 4 and 5 are plan or top views, of the apparatus.

Figure 6 is a plan or top view of the sliding plate F, of the same.

Similar letters of reference indicate corresponding parts.

The cooling-tubes B of the furnace, which receiye the reburnt charcoal from the heating-tubes A, arranged in a well-known manner, restwith their lower ends upon a plate, C, fixed in the brick-work, said plate C being formedwith corresponding apertures D,

that are surroululedby projecting fillets or flanges, be-

tween which'the tubes B fit,l as shown.

On the under surface of' the plate G is formed a number of longitudinal ribs or partitions, c c c, one being situated at each side of every row'of holes D, and across the spaces between these partitions are again formed transverse partitions d, one of which is situated vunder the back edge of everyhole D, thus forming separate compartments E E E, with one of which each ofthe tubes B communicates.

At a slight distance below the lower edges of the partitions c and d, is arrangeda sliding plate, F, resting upon the edges of rollers G, that are hung on pins that project from brackets H, vwhich are fixed to and suspended from the plate G.

' The plate F is thus free to receive a reciprocating motion, in a longitudinal direction, beneath the plate The plate F has a number of apertures, J, corresponding tothe number of apertures D, and oneof which is consequently situated under one of cach of the compartments-E.

The' action of this apparatus is as follows:

The cooled charcoal falls from the lower ends of the cooling-tubes B, through the apertures'D, upon the plate F, filling up the compartments E to a cert-ain extent, a`s indicated in iig. 3.

If now the plate F, whose apertures are not under those of C, be moved slightly to the right, it will carry the charcoal lying upon it with it, and away from the aperture D, and consequently-.a fresh quantity of charcoal will fall from the tubes B, upon the plate F.

If the latter is now moved back to the same extent that it was` moved forward, thev partitions d will prevent the charcoal from moving hack with it, and the charcoal will consequently by such motion be pushed toward the apertures J.

Thus, at every forward and backward motion 0f the plate F, the quantity of charcoal of each compartment :will be first increased by a quantity passing in from the't-nbes B, and itwill then bc pushed. .towardvthe apertures J, until by each backward motion a quantity of charcoal is caused to fall through such apertures into a suitable receptacle, L, which quantity will, of course, eventually be equal to that which passes into the compartments E from the. tubes B, atevery forward motion of the plate F.

The requisite reciprocating motion of the plate may be imparted by anysuitable arrangement of mechjanism.

Thus, in the arrangement shown in the drawing, the plates F of the apparatus' to the several furnaces are all actuated by means of one and the same rodM, to which they are connected, in the manner indicated, and which receives a reciprocating motion from a small water-pressure engine, N, which is particularly applicable, on account of the practicallyconstant power given out thereby, corresponding with the nearly constant resistance otfered by the plates F.

The apertures D and J are, in figs. 4 and 6, shown 'as being arranged in alternate rows, but they may as well be arranged as in fig. 5, that is to say, in parallel rows,.as shown.

In this latter position they will be better adapted l to thc furnaces generally in use-in the AUnited States.

Having thus described my invention,-

What I claim as new, and desire to secure by Letters Patent, is-

The apparatus for removing animal charcoal from the cooling-tubes, the said apparatus heilig composed of the plat@J C, with apertures D and compartments E, and operating in 'combination with the reciprocating plate F, which is provided with apertures .I substantially in the manner herein set forth, all arranged as specified.

In testimony whereof', I have signed my name to this specification, in the presence of two subscribing witnesses, this'lst day of February, 1869.
